PageSize不在ExtJS中使用Grid

Question

我想将每页的记录限制为特定数字在网格中应用分页但由于某种原因导致其失败。

任何人都可以说为什么它失败了，或者没有工作？这是Fiddle。

我的商店

    var myStore=Ext.create('Ext.data.Store', {
        storeId: 'simpsonsStore',
        fields: ['busname', 'time', 'typebus',],
        pageSize:2,
        data: [{
            busname: 'ABCD',
            time: '15:30:00',
            typebus: 'AC Volvo',

        }, {
            busname: 'aaa',
            time: '13:30:00',
            typebus: 'Seater',

        },{
            busname: 'AAAA',
            time: '18:30:00',
            typebus: 'Sleeper',

        },{
            busname: 'ABCD',
            time: '19:30:00',
            typebus: 'AC Volvo',

        },]

网格面板

Ext.create('Ext.grid.Panel', {
        xtype :'gridpanel',
        itemId:'busTimegrid',
        pageSize:1,
        title: 'BUS DEATILS',
        mapperId:'getBusTime',
        store: Ext.data.StoreManager.lookup('simpsonsStore'),
        columns: [{
            header: 'Bus Name',
            dataIndex: 'busname',
            editor: 'textfield'
        }, {
            text: 'Bus Time',
                dataIndex: 'time',
            xtype: 'gridcolumn',
            renderer: function (value) {
                if (value instanceof Date)
                    return Ext.util.Format.date(value, 'H:i:s');
                else
                return value;
            },
            flex: 1,
            editor: {
                xtype: 'timefield',
                format: 'H:i:s',
                allowBlank: true,
                maskRe: /[0-9,:]/,
            }
        }, {
            header: 'Bus TYpe',
            dataIndex: 'typebus',
            editable:true,
            renderer: function (value) {
                if (Ext.isNumber(value)) {
                    var store = this.getEditor().getStore();
                    return store.findRecord('id', value).get('name');
                }
                return value;
            },
            editor: {
                xtype: 'combo',
                displayField: 'name',
                valueField: 'id',
                editable:true,
                forceSelection:true,
                store: Ext.create('Ext.data.Store', {
                    fields: ['id', 'name'],
                    data: [{
                        id: 1,
                        name: 'AC Volvo'
                    }, {
                        id: 2,
                        name: 'Seater'
                    }, {
                        id: 3,
                        name: 'Sleeper'
                    }]
                })

            }
        }],
        selModel: 'cellmodel',
        plugins: {
            ptype: 'cellediting',
            clicksToEdit: 1,
        },
        listners: [{
            fn: 'onUsernamefieldBlur',
            event: 'blur',
            delegate: 'busname'
        }],
        onUsernamefieldBlur: function (textfield, e, eOpts) {

        if (textfield.getValue() === '') {
            Ext.Msg.alert("Busname can't be empty");
            textfield.setFocus(true);
        }
    },
        height: 200,
        width: 400,
            dockedItems: [{
            xtype: 'pagingtoolbar',
            store: myStore,   // same store GridPanel is using
            dock: 'bottom',
            displayInfo: true
        }],
        renderTo: Ext.getBody()

    });

添加了pageSize，但分页仍无效。我似乎没有发现问题是什么。我怎样才能找到我错过的确切内容？

Answer 1

从你的问题中我发现你想要实现与实际分页不同的局部分页。要首先执行此操作，您需要提及内存代理并启用分页，将以下代码放入您的商店。

   proxy: {
           type: 'memory',
          enablePaging: true
    }

我可以通过将上面的代理放在你的小提琴中来获得分页。

（代表OP发布）。

在我遵循Surya prakash建议的解决方案之后，这很好。

Ext.application({
    name: 'Fiddle',

    launch: function () {
        run();
        window.show();
    }
});

function run() {
    var myStore=Ext.create('Ext.data.Store', {
        storeId: 'simpsonsStore',

        pageSize:2,
        proxy: {
           type: 'memory',
          enablePaging: true
    },
        data: [{
            busname: 'ABCD',
            time: '15:30:00',
            typebus: 'AC Volvo',

        }, {
            busname: 'aaa',
